Study characteristics
Methods	Randomised controlled trial
Participants	Inclusion criteria: All babies admitted to the special care nursery at 2 hospitals during the study period with uncomplicated hyperbilirubinaemia Exclusion criteria: Babies with serum bilirubin levels close to the exchange transfusion limit Elevated direct bilirubin Hemolytic disease Congenital anomalies Mean (SD) age in days at recruitment: Intervention = 5.0 (1.36) Control = 4.9 (1.34) Mean (SD) body weight in kg of participants: Intervention = 2.76 (0.2) Control = 2.72 (0.18)
Interventions	Intervention: single phototherapy compact blue light, 5 bulbs, with curtains (N = 31) Control: single phototherapy compact blue light, 5 bulbs without curtains (N = 32) White plastic curtains (number of sides not reported)
Outcomes	Mean decrease in bilirubin after 12 and 24 hours Adverse effects reported (hyperthermia, diarrhoea, dehydration, "others")
Notes	Study conducted in Haji Adam Malik and Pirngadi Hospitals, Medan, Indonesia, from May to December 2009
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"Simple randomisation". Method of generation of random sequence not reported
Allocation concealment (selection bias)	Unclear risk	Not described in the manuscript
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants: neonates by definition blinded, but parents not blinded. Clinicians/Nurses not blinded. The type of intervention may have influenced handling of the baby by parents and healthcare providers
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Not reported. We judged bilirubin measurement to be an objective measurement not affected by lack of blinding
Incomplete outcome data (attrition bias) All outcomes	Low risk	1 dropout in the intervention group 2 dropouts in the control group
Selective reporting (reporting bias)	Low risk	No protocol available. All expected outcomes and all those in the methods reported
Other bias	Unclear risk	No other source of bias identified
